[PATCH v2 2/3] mci: core: add broken_cd device parameter

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

Sometimes a broken card-detect is not a general issue affecting all
boards, but only a given board. Allow setting broken_cd for such boards
via a device parameter.

v1 -> v2:
  - replace Kconfig option with device parameter (Marco, Sascha)
